simplify sqrt(-3)*sqrt(-15)

simplify

- 3 \cdot - 15

- 35

Decimal Notation

- 6.70820 \dots

Solution steps

- 3 - 15

- 3 = 3 i

= 3 i - 15

- 15 = 15 i

= 3 i 15 i

Apply exponent rule:

aa = a^{2}

ii = i^{2}

= 3 i^{2} 15

= 315 i^{2}

15 = 35

= 335 i^{2}

Apply radical rule:

a a = a, a \geq 0

33 = 3

= 35 i^{2}

Apply imaginary number rule:

i^{2} = - 1

= 35 (- 1)

Multiply the numbers:

3 (- 1) = - 3

= - 35

9 w - 4 \geq 7 + 11 w

- x^{3} + 7 x^{2} - 14 x + 8

\frac{80}{49}

2 (\frac{1}{3})^{2}

x - (- 2) = 4
